Abstract
Each of several routers connected to a LAN elects the same router as the designated router for a multicast group identified by a multicast address. Each of the several routers implements a method for electing the designated router. The method includes in one embodiment, generating several values corresponding to the several routers, respectively. The several values are generated as a function of the several routers' IP addresses, respectively, and an IP address of a first multicast group. The values, in one embodiment, are then compared to determine which is the largest. Thereafter each router elects as the designated router for the multicast group, the router corresponding to the largest value.
